In our daily lives, we often encounter aerosol cans in various forms - whether it's the deodorant we use in the morning, the disinfectant spray we rely on for cleanliness, or the spray paint we employ for artistic endeavours. However, have you ever wondered about the environmental impact of these ubiquitous cans?

“Synergy take all types of Aerosol”

Around 60% of aerosols are crafted from tinplated steel, while approximately 40% are fashioned from aluminium. The good news is that both of these metals are recyclable, presenting an opportunity for us to reduce our carbon footprint and contribute to a more sustainable future.

Aerosols in Everyday Life

Aerosol sprays have become a staple in households worldwide, offering convenience and practicality with their easy-to-use, leak-resistant design. From hair styling to household cleaning, here are some common aerosols you may find in your home:

- Hair spray

- Deodorant sprays

- Oven cleaners

- Vegetable oil sprays

- Medicinal sprays

- Insect repellents

Aerosols in the Workplace

The versatility of aerosol sprays extends beyond the confines of home, finding frequent use in various commercial settings. Here are some examples of where aerosols are commonly employed in workplaces:

- Spray paints

- Lubricants

- Cleaning fluids

- Air fresheners

Environmental Impact of Aerosol Pollution

While aerosol cans offer undeniable benefits, it's essential to acknowledge their significant environmental implications. Before reaching for another spray, consider these environmental concerns that may give you pause:

Volatile Organic Compounds (VOCs)

In the past, chlorofluorocarbons (CFCs) were prevalent in aerosols, causing substantial damage to the ozone layer. Although banned, modern aerosols primarily contain volatile organic compounds (VOCs), which contribute to air pollution. Research indicates that aerosol products emit more harmful VOCs than all vehicles in the UK combined, posing health risks and environmental harm.

Climate Change

Aerosols influence climate dynamics, scattering sunlight and altering Earth's radiation balance. While some aerosols may cool the planet by reducing solar radiation, others, like black carbon, contribute to global warming by absorbing and emitting radiant energy.

Cloud Formation

Increased aerosol pollution can disrupt cloud formation, impacting precipitation patterns. Dirty air can lead to thicker clouds and altered rainfall patterns, exacerbating weather extremes and affecting agricultural productivity.

Hazardous Waste

Although aerosol cans themselves are recyclable, their contents pose a threat if not disposed of properly.

Pressurised cans containing residual liquid or gas are considered hazardous waste. Proper disposal, either through household collection or recycling facilities, is crucial to mitigate environmental risks.

In conclusion, while aerosol sprays offer convenience, their environmental impact warrants careful consideration. By adopting responsible usage and disposal practices, individuals and businesses can minimise their ecological footprint and contribute to a healthier planet.One key aspect to consider is the lifespan of the contents within these aerosol cans. Often, they last for a considerable period. So, what should you do if you find yourself with full or partially full aerosol cans that you no longer need immediate access to?

Firstly, if you have the space, storing these cans for future use is a prudent choice. Whether it's spray paints awaiting your next artistic project or spare deodorants for when you run out, finding a storage space for them can prevent unnecessary waste.

Alternatively, if storage space is limited, consider donating these cans to local charity shops or giving them to friends, family, or neighbours who may have use for them. It's a small gesture that can make a big difference in reducing waste and promoting reuse.

However, if disposal is unavoidable, it's crucial to handle full aerosol cans responsibly, especially considering their potential as hazardous waste. For businesses, arranging hazardous waste collections is the recommended approach. This involves placing full or partially full aerosol cans in designated hazardous waste bins and scheduling collection by licensed waste carriers.

Households, on the other hand, can visit out-of-home recycling centres equipped with hazardous waste disposal facilities to dispose of full aerosol cans safely.

Before disposal, it's imperative to ensure that the aerosol cans are empty. A simple shake and spray test can confirm this. Once empty, remove any detachable parts, such as the lid, and dispose of them according to the relevant recycling stream.

Crushing, piercing, or flattening aerosol cans should be avoided, as they are pressurised containers that may pose risks if tampered with. Leave the nozzle intact, even if it's made of plastic.

When it comes to actual disposal, households can typically place empty aerosol cans in their household recycling bins, while businesses can utilise commercial metal recycling bins or hazardous waste bins.

By following these guidelines, we can all play a part in responsibly managing aerosol cans, minimising waste, and working towards a greener, more sustainable future for generations to come. Let's embrace sustainability, one aerosol can at a time.
